I wanted to mix it up a bit and write a story of Elijah Mikaelson's daughter
Her name is Elizabeth Emma Mikaelson but no one knows that yet including her
Elijah didn't know he had a daughter with him thinking he couldn't procreate but he had a relationship with a powerful witch that made a spell so she could have children with him but she didn't know that he would leave her as soon as she got pregnant
He didn't find out about her until his niece started to go to the same school as his daughter
When the unknowing nine year old daughter of Nick Torres finds herself tangled up with NCIS, things take a turn for the worse. With her adoptive family murdered, a strange man to find, and bad people after her... How will she survive? Nick Torres doesn't even know he has a daughter until the dots are connected in Abby's lab. Even if she can settle back into normal life, how will she cope when her dark past comes knocking?
Crossover with Criminal Minds like halfway through
